(1) The Base FFT Lines represent the size of the raw processed FFT and are the number of lines returned if no adjustments are made
for decimation and filtering. Control of application of relevant factors for the applied decimation and filtering is provided in the
SpecialRequest member of the CM Record Request structure
(2) Or if -60 dB filter is applied (Aeroderivative Measurement Type)
(3) And the standard -24 dB/octave filter is applied.
